The standard Western spelling for this type of Japanese knife seems to have settled on "petty knife" (effectively a loanword back into English); the references are a bunch of Western knife/cook shops that use and define 'petty knife' that way. (If you google for 'petit knife' it will assume you mistyped 'petty knife'.)

I add "kitchen" to "small knife" because if you don't want the technical cheffy term it's helpful to know that it's specifically a kitchen implement. (Ref: Daijisen defines it as "小形の洋包丁。野菜や果物の皮むき用". I'm amused that there it's defined as a Western-style knife and in the West we define it as a Japanese-style knife, incidentally.)

I was surprised to see hits for "petit knife", which I'd suspected was 和製英語. Many are fro sites selling Asian products.
